TRUCK FO R CABLE- RAILWAY CARS.

SPECIFICATION forming part of Letters Patent No. 405,691, dated June 25, 1889.

Application filed AprilZZ, 1889- Serial No. 308,063. (No model.)

To all whom it may concern.-

Be it known that I, SUMNER A. BEMIs, a citizen of the United States, residing at Spring field, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Trucks for Cable-Railay (Jars, of which the following is a specification.

This invention relates to improvements in grip-trucks for cable-railway cars, particularly in means comprised in said trucks for supporting the grip-carrying beam, whereby the beam may be readily applied and detached from the truck, and when carried thereon it ismost efficiently cushioned against jar or shock; and the invention consists in the construction and combination of the various parts, all substantially as will hereinafter more fully appear, and be set forth in the claims.

In the accompanying drawings, Figure 1 is a side elevation at one end of a cable-railwaycar truck, showing a portion of the car-sill supported thereon, and also the pocket for carrying one end of the grip-carrying beam, some of the parts adjacent the journal-box for the car-wheel axle being broken away, and the said beam-carrying pocket shown in central vertical section. Fig. 2 is a horizontal section 011 the line 2 2, Fig. 1, with parts below the plane indicated by such line in plan view, a middle portion of the journal-box being broken away to more clearly show the top of the beam-carrying pocket. Fig. 3 is an end elevation of the parts seen in Fig. 1, the carsupporting spring being removed; and Fig. 4 is a perspective View of the beam-carrying pocket.

I11 the drawings, A represents a car-wheel near the end of the axle B for one end of the truck, said axle being projected beyond the outer face of the'car-wheel and supports the box C, which has forwardly and rearwardly projecting steps a, preferably integrally cast therewith, on which, through the medium of springs D, between said steps and the sill of the car, the car-body is supported, and said body is provided with pedestals E over each j ournal-boX, which are bifurcated, having the inner and outer pending portions 1) and (Z, which play through openings 6 in said steps a and serve to prevent undue lateral chucking of the car-body on the trucks, and said pending pedestal portions 1) and (Z are each also bifurcated to fit over the j ournal-boX, as usual in railway-oar trucks.

Each step a comprises practically vertical inner and outer walls, which range in parallelism forwardlyor rearwardly, as the case may be, and are curved at their extremities to meet each other to form the sockets f for the base of the springs I).

G represents the pocket for carrying the grip-beam, one end portion of which beam is shown at F, and said pocketan improved design of which is shown in perspective in Fig. 4comprises opposing side or cheek pieces g g, connected by suitable cross webs or braces 7L 2', one of which affords a horizontal support for the bottom of the grip-beam at its portion adjacent its end, and the other forms a vertical wall for confining the gripbeam against undue endwise movement, a slight compression of the rubber cushionsj, comprised in said vertical wall, serving to permit a slight longitudinal yielding of the beam at the time of suddenly stopping or starting the car, and the similar cushion j on the horizontal brace-web insures an easy horizontal support of the beam. Each cheek-piece g has upward extensions m and m at its forward and rearward portions, respectively, the opposing forward extensions being preferably connected by a horizontal tubular brace Z and by a suitable bolt or rod 02, passed through the inner and outer walls of the step toward the forward end of the truck (or the rear end, as the case may be, according to which is the forward axle-j ournal of the truck) and through the perforations 7c in the interposed cheekpiece extensions on m, and axially through said tubular brace Z the said pocket is supported and adapted to be swung on said bolt, and when in its normal beam-supporting position, as particularly shown in Fig. 1, it is held by a removable bolt 17, passed through the walls of the other step a and through the perforations It" in the extensions m of the opposing cheek-plates. The said bolt 19 is to be, as will be obvious, held against displacement by a linchpin or equivalent means, and the pivotal bolt or rod 72 is also removably connected in the truck, whereby, if desired, the pocket-frame may be removed from the truck.

It will be observed that, as shown in the drawings, the main portion of the pocket or supporting frame G lies under the journalboX, While the supporting-extensions m on project upwardly at the front and rear thereof.

On desiring to insert or remove the gripbeam, the bolt 19 is withdrawn, when the pocket drops, swinging from its pivoted extension end on, as shown in the dotted lines in Fig. 1.

What I claim as my invention is 1. The combination, with a suitable part of a railway-oar truck, of a pocket-frame for carrying a grip-beam, consisting of opposing cheek-pieces having intermediate horizontal and vertical walls 77, i, and by one end pivotally hung on and by its other adapted to be detachably connected with the truck, substantially as described.

2. The combination, with a suitable part of a railway-car truck, of a pocket-frame for carrying a grip-beam, consisting of opposing cheek-pieces having intermediate horizontal and vertical walls h 1', provided with cushions, and by one end pivotally hung on and by its other adapted to be detacliably connected with the truck, substantially as described;

3. The combination, with the journal-box provided with forwardly and rearwardly projecting steps having vertical openings there in, of the pocket-frame for carrying the gripbeam, consisting of opposing cheekpieces having upwardly-extended projections m m, and provided with the intermediate cushioned horizontal and vertical walls h i, and said frame, by one of its opposing pairs of eX- t-ensions, being pivotally hung within the walls of one of said steps and by its other pair of extensions adapted to be detachably supported within the walls of the other of said steps, substantially as described.

4. A grip-beam-carrying pocket-frame consisting of vertical opposing cheek-pieces provided with vertical and horizontal intermediate transverse walls provided with cushions, substantially as described.

5. A grip-beam-carrying pocket-frame eonsisting of vertical opposing cheek-pieces, each provided with forward and rearward upward projections m m and united by the transverse vertical and horizontal walls provided with cushions, substantially as described.
